entry/invalid-date

A date or datetime field can’t be read. Dates are ISO 8601, such as 2025-12-12; datetimes are RFC 3339, such as 2025-12-12T09:30:00+08:00, and one without an offset is in site.timezone.

Example

---
title: Pew
date: Dec 12 2025
---

Fix

Write the date in ISO form, date: 2025-12-12; the help suggests it when the date can be read another way.
